Unformatted text preview: Î» in the TE 10 mode but not the TE 11 or TM 11 modes. Q4*: Consider the TM 11 mode of the rectangular wave guide in Figure 9.24, G p.408. Calculate the time-averaged Poynting vector and EM energy density and obtain the velocity of energy transported down the wave guide from these quantities. Compare with the group velocity obtained from the dispersion relation for this mode....
